To all Awhom 'it may concern: v

lic it linown that l, (.iianmcs E. ZAlriii,

` *a rilizen ol' the l'nited States, and a resident ol' Aurora. county of Kane, and State of Illinois, have invented certain new and uset'ul Improvements in "heel-llubs, of which the follow-ing is a specification, and which are illustrated in the accompanying draw- 1 ings. i'ormingir a part thereoft".

The invention appertains more particularliI lo the hubs ot' automobile wheels: its

Fie'. -l is a view similar to Fi@l 2, with the.

locking` meehanism in dill'erent position; and

Fig. is a detail oi' the loi-hinar lateh. The huh comprises a sleeve 10, adapted to receivethe axle 'l1 and to he either rotatable thereon, as shown in Fig. l. orkcyed there.- to as shown at l2 in Fig. Il. The sleeve 10 is provided with a radial flange '1.3 at its 'inner end, and is externally threaded at ,the threaded portion of lthe its outer end.

A casing, 14; incloses and fits upon the sleeve 10, hut is spaced apart lfrom its threaded portion. The casing is provided with a radial flange 15,`adapted to' engage and be secured tothe {iange 13 against relati ve rotative movement, as by means of bolts 16, the flange 15 also providing means for4 the attachment of the yinner series of spokes in a .so-called wire wheel. 'lhe outer end ot the casingr 14. is enlarged, as shown at 17, the peri hery of the enlarged portion being.: provided with pertorations, as 18, for the attachment of the outer series of spokes.

A cap 19 covers the open end ol' theI casingl 14,. and is provided with an internally threaded tubular stein 20, ada )ted to engage sieeve 10. The stem 2() is provided with av radial (lange 21, adapted torhear against the'end of the body portion of the casing 14, the periphery of this flange being provided with ratchet Specification. of Letters Patent.

teeth, as showin at 22. A latch or pawl for coperating with the ratchet teeth is pivotal'ly ataiched tothe outstanding dial flange 4 ot' the enlarged outer end o1' the casina,` and is-normally held in engagement with the ratrhetfteeth by means of a spring' 2a. .x

A controlling lever 2li. pivoted to the flange 2l. engages the outer end of the pa wl 23. andailorda means i'or rocking the pawl on its pivot to disengage it frolnthe ratehet teeth. 'l `he h ver ti piojeets through an aperture 2T in the periphery of the enlarged portion 17 of he casing.

'llie inner ei id oi the lever 2li is provided with a eam lale 2S. engaging: the outer end 25) of the pawl 23, .and a shoulder Il() which comes into engagement with the side of the pawl when the latter is tilted out of engagement with the ratchet. teeth. and thus locks the pawl in it.g released' position. l

'Ihe ratchet teeth 2;! are so pitched that the tzap 1U' |na he turned up upon the sleeve 1t), the pawl e icliing over the teetl|.'g\'\"lnn it is desired lo remove the rap, the lever 2U is manually moved 'from the position shown im Fig: l to that shown in Fig. 2, thereby disenraging the pawl .from the ratchet' teeth :nd permitting' the cap to he unserewei'l.

'Eheratrhetz ndpawl mechanism for loek img|` he hnhea )isnot olmy invention: my mm'owment fonsistingiY in the lever device l`or controlling; the pawl aml holding it in released position. \\"hile l' have. showna preferred form ol eonstruetion` l do not desire to be specilirally limited thereto` eithe' as to the vl'orm and (manner o1' mounting.r ofthe eollrolling lever` or as to the form of the lookin,"r mechanism for :securing:V the huhcap.

I claim 'as nl y inventionl. A wheel huh comprising, in combina tion1 an axle-r1:eeiving` sleeve.` a casing.r fitting on and non-ritatahlel with reference to the sleeve and hai iuplr its outer end` enlargeih'a cap for eoveri. 1g' the outer end ol the, easilig and being in threaded engagement with thei Sleeve, a spring: latch mounted within the enlarged end o* the easingV 'and engageable with the cap, :z nd a lever projectingr through the periphery ot the enlarged end ol` the easingr for con lrolling` the latch.

2. A wheel huh eom n'ising, in combination, an axler zeiviiig sleeve, a casing fitting Ion and nonritatablefwitli referente to the sleeve and having its outer end enlarged, a cap for covering the outer end of the casmg and being in threaded engagement with the sleeve, 'a spring latch mounted within thev enlarged end of the casing and -engageable with the cap, and a lever projecting through the periphery of the enlarged end ofthe casing for controlling theglatch and havjing a shoulder for holding the latch in release position.

3. A wheel hub con'iprising, in combination, an axleq'eceivin'gr sleeve, a casing 'fitting on and non-rotatable with reference to the sleeve and having its outer end enlarged, a rap. for covering the Outer end of the casing,r and being in threaded engagement with the sleeve, a spring latch mounted within the enlarged end of the casing and a lever having at its inner end a cam face adapted to tiltthe latch out of engagement with the cap and a shoulder for holding the latch in, disengaged position.

4. A wheel hub comprising, in combination, an axle-receiving sleeve, a casing fitting on and non-rotatable with reference to the sleeve and having its outer end enlarged, a' ca p for covering the outer end of the casing and being in threaded engagement with the sleeve, and having a radially toothed flange,

vu spring paivl engageable with the flange axle-receiving sleeve, a casing removably t'- ting on the sleeve and interlockedltherewith against relative rotative movement, n.cap covering the end of the casing and interlocking with the sleeve b v a rotative movement, a latch for preventing relative movement of the cap and casing and mounted on one of said parts, and a radially projecting lever for actuating the latch.
